iterator used to traverse points
<p>
This class (and subclasses) are used to iterate over points. Use it only in conjunction with <a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> (i.e., the adaptor framework).<p>
Typical use is: <pre>
<a class="el" href="a00590.html" title="defines dataset interface">vtkGenericDataSet</a> *dataset;
<a class="el" href="a00602.html" title="iterator used to traverse points">vtkGenericPointIterator</a> *it = dataset->NewPointIterator();
for (it-><a class="el" href="a00602.html#9e56e087ebf7e8b72bcb183908363be0">Begin()</a>; !it-><a class="el" href="a00602.html#d24531a667a7cf564a0023f253a84e23">IsAtEnd()</a>; it-><a class="el" href="a00602.html#cc7e6f64cad6c9153d9457e04f670881">Next()</a>);
